# An example CMakeLists.txt for the sanitizers example, showing how to
|
||
|
|
# enable sanitizers in a debug build.
|
||
|
|
# It uses generator expressions, to set additional flags when the build type
|
||
|
|
# is Debug.
|
||
|
|
#
|
||
|
|
# To try this out, first create a build directory for a release build,
|
||
|
|
# and do a release build, e.g.,
|
||
|
|
# % mkdir build-rel
|
||
|
|
# % cd build-rel
|
||
|
|
# % cmake SRC_DIR -DCMAKE_BUILD_TYPE=Release
|
||
|
|
# % make
|
||
|
|
#
|
||
|
|
# Run the examples and see that they crash.
|
||
|
|
#
|
||
|
|
# Then create another build directory and do a debug build:
|
||
|
|
#
|
||
|
|
# % mkdir build-dbg
|
||
|
|
# % cd build-dbg
|
||
|
|
# % cmake SRC_DIR -DCMAKE_BUILD_TYPE=Debug
|
||
|
|
# % make
|
||
|
|
#
|
||
|
|
# where SRC_DIR is the directory containing the source and CMakeLists.txt,
|
||
|
|
# e.g., .. if your build directories are placed in this directory.
|
||
|
|
#
|
||
|
|
# Run the examples and verify that the sanitizers find the errors.
|
||
|
|
#
|
||
|
|
# If you want to see the actual commands run during the build, for instance
|
||
|
|
# to verify that the correct compiler flags are used, you can do
|
||
|
|
#
|
||
|
|
# % make VERBOSE=1
